This is an internal API: no architecture exports this. Whoever is
trying to use it needs to use the correct API, so this is the wrong
patch.
There is a declaration for it in arch/parisc/include/asm/cacheflush.h.
There are a bunch
of callers in mm. The interface in documented in
Documentation/cachetlb.txt. We currently
use it in copy_to_user_page and copy_from_user_page.
